“We’re all happy,” said Foster, 68. “And you know, for some reason, the two of us, one plus one makes four instead of two. So it seems like it’s interesting news to people, so we’re just gonna roll with it.”

Foster also recalled the moment he first met McPhee back in 2006 when she was a contestant on “American Idol” and how he told the actress-singer at the time that she had a “great, great future ahead of her.”

“I was bragging,” the Grammy winner said, adding that there “sure” was a spark during that first meeting.

Earlier this month, a rep for McPhee confirmed the pair’s engagement to Fox News.
